They probably added ascension for day one players who earned guns like fatebringer late, for just one last chance to use it in its "prime". I didn't earn mine until June, but it would've been best if they had never added it. Ultimately, the point of moving beyond old gear is so players actually try new gear. If fatebringer continued on players would miss out on excellent gear that was ignored because of an unwillingness to try new things. Why is it so bad that we have to leave it behind? Would you have not done endgame content, and tried to earn all the rewards anyway?
